A magnetic control-type flow control valve, comprising: a metal tube unit with a top end portion, a bottom end portion and an intermediate portion between said top and bottom end portions, said intermediate portion having an outer wall surface that is formed with an annular recess; a driven magnet ring disposed rotatably in said intermediate portion of said metal tube unit, said driven magnet ring having a bottom end and an outer peripheral wall with a first polarity; a rotatable circular valve piece disposed in said intermediate portion of said metal tube unit and connected to said bottom end of said driven magnet ring, said rotatable valve piece having a bottom surface and being formed with a pair of diametrically opposite first openings; a stationary circular valve piece secured in said bottom end portion of said metal tube unit, said stationary valve piece having a top surface in tight contact with said bottom surface of said rotatable valve piece and being formed with a pair of diametrically opposite second openings; and a driving magnet ring sleeved on said outer wall surface of said intermediate portion of said metal tube unit in said annular recess, said driving magnet ring having an inner peripheral wall with a second polarity opposite to said first polarity, said driving magnet ring being rotatable to rotate said driven magnet ring therewith so as to rotate correspondingly said rotatable valve piece relative to said stationary valve piece between a first position, wherein said first and second openings are aligned, and a second position, wherein said rotatable valve piece covers completely said second openings.
